Value Collection FWSIS150-025BX Sae Flat Washer Steel 25pk

Product Description

The VALUE COLLECTION FWSIS150-025BX is an SAE flat washer designed for use with 1-1/2 inch screw sizes. Manufactured from steel with a plain finish, this washer distributes load across fastened surfaces to prevent pull-through and surface damage. The 1-9/16 inch inside diameter provides proper clearance for the fastener shank, while the 3 inch outside diameter delivers a broad bearing surface. At 5/32 inch thick, the washer provides solid, consistent support under bolt heads and nuts. This package contains 25 washers, making it a practical quantity for job-site use or shop stock. Installers across mechanical, structural, and industrial trades will find this a reliable standard hardware item.

SAE flat washers of this size are commonly used in heavy mechanical assemblies, structural connections, and industrial equipment installations where a larger bearing surface is needed compared to USS-series washers. The 1-1/2 inch screw size designation makes this washer appropriate for heavy-duty bolted connections in equipment mounting, framing, and machine assembly applications. The plain steel finish suits interior or protected environments where corrosion resistance is not the primary requirement.

Installation Notes

Flat washers are installed by placing them over the fastener shank before threading on the nut or seating the bolt head. Ensure the washer inside diameter is compatible with the fastener shank diameter before assembly. Plain steel finish washers should not be used in wet or corrosive environments without additional protective measures. Follow applicable mechanical or structural codes for fastener assembly torque requirements based on the specific application.
